To all whom it concern:

Be it known that we, OSCAR H. PIEPER and .ALPHDNSE F. FEEDER, oflztochestcr, in the county of Monroe and State of New Y rk, haveinvented certain new and useful .lmproveinc s in Electrolytic Cells;and. we

do hereby declare the following to be a full,

clear, and exact description of the same, reference bei" g had to theaccompanyin draw ings, farming and to the" rreference-numerals markedthereon. i i v The present invention relates to elect-ro- 1 tic cells)articclarl" of the toe cmplo 'ed 3 l .Vl Ii as alternatingcurrentrectifiers which em body an electrolytic containing receptacleforming an inert electrode and an active electrode arranged in thereceptacle, and it has for an object-to provide an improved constructionwhich shall have a maximum radiating surface to dissipate the heat-gen-V crated in the cell.

Another object is to collect the preciph titted matter in such a mannerthat it will not interfere with the circulation of the electrolyte, noract to short circuit the cell by connecting the two electrodes.

To these and other ends the invention consists in certain improvementsand combinat-ions of parts all as will be hereinafter more fullydescribed, the novel features bei'ng pointed out in the claim at the endof the specification.

Inthe drawings; Figure 1 is a plan view of the receptacle electrode;Fig. 2 an end view; Fig. 3 is a vertical longitudinal section; and Fig.t is a detail horizontal section.

The, present embodiment of the invention employs an electrode chamber 1open at its top 2 and having hollow ribs 3 each extending on op iositevertical walls and around the bottom to receive the electrolyte andquickly dissipate the heat contained therein.

11 order to further increase the adiation of the cell, there areprovided lmllow radiating chambers l preferably arranged in two seriesthe members of which are connected by passageways?) at their tops andbottoms. One member of each series is con? ncted to the top and thebottom-of the 61 9- a part of this speeiiication,

These radiating chombers are formed oftwo vertical connected at their tops and bottonis and with these top andbottom portions the passage- Ways 5,6 and 7 connect.

above the radiating to be filled to their top with the. electrolyte,

thus providing a perfect circulation, and

the connections or passageways 6 and 7 by leading from upper and lowerpo tions that connect the legs of the units a prevent any dead spacesbeing formed above or below the connections. The ends of chambers 4 haveopenings alined with paschainber is materially less The projection. oftheelectrolyte chamber chambers permits the radiating chambers sages 5,6 and 7 and closed by screw plugs 8 to permit the cleaning of thechambers.

Arranged in the electrode chamber is the active electrode 9 which inthis instance is in the form of a stick be supported by a perforated andremovable closure 10 for the electrolyte chamber and carry a bindingpost 11 by which a condoctor is secured, the other binding post 12 beingcarried by a plug 8 in order to be electrically connected to the hollowelectrode 1. F The electrode 9 has its lower end arranged above thebottom of the'passage ways 7 obd as the electrolyte chamber 1 dependsbelow these passageways a comoartof aluminum. It may most provided toliold the precipitate sb that the; latter cannot interfere with theoirculation or cause a short circuit between the electrodes 1 and 9.

An electrolytic cell constructed in accordance with thisinvent-ion is.inexpensive to be cast in one piece sothat it is not liable to leak.Further the parts are so formed that a maximum radiating surface isobtained without unduly increasing the size of the cell.

We claim as our invention:

An electrolytic cell comprising a hollow electrode chamber and radiatingchambers a. with passageways connecting at thef tops and bottoms andalso conneciiing them with electrode chamber, the bottmn of the latterbeing lower than the bottom 0'? the other chambers and forming a.sediment col- 5 lecting pocket, said chambers and passageways beingformed in an integral casting having apertures in alinement with thepussagcwalis and clean out plugs fitted in said apertures.
